In most cases your plumbing will be similar to the plumbing shown. Notice that the first Check Valve is plumbed in after the filter. This prevents the filter from being back-washed by the water draining from the panels when the pump shuts off. The Three-way Valve either diverts the water to the solar system or directly back to the pool.
The pump can be turned off and on with the manual switch located inside the controller front panel. When this is completed drain the solar loop using the System Drain Valve below the pump (On DBSA systems the System Drain Valve is behind the shroud).
Shut-off valves must perform a high number of strokes, and breakage is a risk. Excessive vibrations or oscillations can also reduce the lifespan of a valve. The challenges for the heat tracing of the bonnet are higher, as a possible crystallization of the fluid within the bellows could lead to a failure.
Shut-off valves are often manually operated or equipped with an electric rotary actuator. In molten salt applications, a shroud-less bellows seal design may also be used. Shut-off valves must perform a high number of strokes, and breakage is a risk. Excessive vibrations or oscillations can also reduce the lifespan of a valve.
This prevents the filter from being back-washed by the water draining from the panels when the pump shuts off. The Three-way Valve either diverts the water to the solar system or directly back to the pool. The Check Valve on the solar return pipe prevents the water from flowing backwards through the solar system when the solar system is shut off.
The first part will focus on how specially tailored control valves can overcome the challenges inherent in solar power production. Solar energy is a viable alternative to fossil fuels and nuclear power. It’s safe, climate-friendly and plentiful, especially in the Earth’s sun belt.

2-way valves, also known as on-off valves or shut-off valves, regulate the fluid flow by allowing or blocking it completely. They are commonly used in simple on-off applications where the flow needs to be started or stopped. 3-Way Valves: 3-way valves have three ports and can redirect fluid flow between two different paths. They are crucial for ...
